test(operator): fix editStatus to use fresh resource version (kroxylicious#3817)

The deploymentChecksumUpdatesWhenOpenshiftRouteHostAssigned test
was using the stale bootstrapRoute variable instead of the fresh
resource passed to the editStatus lambda. This prevented the retry
mechanism from working correctly, causing 409 Conflict errors.

Changes:
- Use lambda parameter 'r' instead of stale 'bootstrapRoute'
- Use editOrNewStatus() to preserve existing status fields
